Quantity:

The attached first and second photos were taken on the installation and commissioning of LHC model Column type I Beam Welding Machine (I Beam is the synonym of H Beam) at Wuxi JACK.  (Fig.1)

1.     Working Process of LHC model Column type I Beam Welding Machine:

The below photo indicates the on site layout of LHC Column type I Beam Submerged Arc Welding Machine in a steel structure facility:  (Fig.2)

Fig2 - H Beam Gantry Welding Machine 13

1)     By means of travel cart, the assembled and tack welded H beams from the previous station of H Beam Assembly Machine are put on the 60° Hydraulic Overturning Rack;

2)     By means of the 60° hydraulic overturning rack, the H Beam is turned into 45° fillet welding position for demanded orientation in the LHC Column type I Beam SAW Machine;

3)     During SAW welding stage in the LHC H Beam Welding Machine, and controlled with automatic arc seam tracker, the welding torch moves in the three axes of X/Y/Z, making precise alignment on welding seam all the time: (Fig.3

4)     The definition on the X/Y/Z axis in LHC Column type H Beam Welding Machine:

a)       X Axis in LHC H Beam Welding Machine:

      i.           This is for modulating the welding torch transverse movement along the long beam of the machine body;

     ii.           This movement can be controlled with handwheel (It is true with LHT T frame H Beam Gantry Welding Machine and LHAZ& LHAC gantry frame I Beam Submerged Arc Welding Machine also). Please check below picture marked in red color round: (Fig.4

Fig4 I Beam SAW Machine 18

    iii.           Note: Some customer request motor control this direction movement. Under such condition, we install a motor on the transverse beam, and have toggle switch on the operating pendant to manipulate it;

b)      Y Axis in LHC H Beam Welding Machine:

This is for controlling the welding torch vertical movement along welding arm, motor drive. It is accomplished with toggle switch on operating panel of the LHC Column type H Beam Welding Machine;

c)       Z Axis in LHC H Beam Welding Machine:

This is for managing the column trolley traveling forward and backward along the rail during working process (Including both SAW and idle running) of the LHC I Beam SAW Machine: This movement is realized with trolley travel.



2.     How to Keep Stability in Column structure of LHC H Beam Welding Machine?

1)      As can be checked from its structure, for this LHC model Column type I Beam Welding Machine, the machine body of trolley-column-beam has two apparent “issues”:  (Fig.5)

Fig5 H Beam Welding Machine

a)       The moving trolley structure is not as stable running as the gantry frame structure in LHA series H Beam Gantry Welding Machine, or the T frame in LHT I Beam SAW Machine. At least looks like this;

b)      The moving trolley structure has smaller area for putting function components compared with LHA gantry and LHT T frame I Beam Welding Machine;

2)      Consequently, to make stable running in both SAW welding period and idle travel stage in the LHC Column type H Beam Welding Machine, and do not have a cramped deployment,

Wuxi JACK takes below actions in designing and manufacture of LHC Column type I Beam SAW Machine:

a)       The moving trolley is double drive with double shaft in VFD (variable frequency drive) manner;

b)      Welding speed is adjusted with turning knob within 10-fold range, and displayed in digital on operating pendant of the LHC model I Beam Submerged Arc Welding Machine;

c)       Instead of put on the trolley or on the beam, control board of the LHC Column type H Beam Welding Machine is integrated inside column, with operating pendant fit on the door. Check below picture marked in red color square frame: (Fig.6

Fig6 I H Beam Welding Machine

d)      Trolley base has 30cm height, with transmission units of motor reducer fit inside. This also increases stability of the moving trolley in the process of LHC Column type I Beam SAW Machine working;

e)      The transverse overhang beam is kept as short as possible: extension 1500mm.
